A modular switch and its data exchange method

Abstract

In order to solve the problem that the management module of the existing modular switch has relatively single functions and is likely to cause waste of resources, the present invention discloses a modular switch and a method for exchanging data thereof, wherein the modular switch includes: a switch backplane and at least two Each switching service module includes the same number of data channel interfaces as other switching service modules, each data channel interface of each switching service module is directly connected to a data channel interface of another switching service module, and the same switching service module The switching service modules connected to each data channel interface of the service module are different from each other, and the lines between the data channel interfaces are arranged on the backplane. Directly connected, so that the management module is no longer needed to avoid waste of resources.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a modular switch and a data exchange method thereof. Background technique [0002] A modular switch in the prior art generally includes a switch backplane, a switching service module, and a management module. A typical modular switch architecture is as follows: figure 1 shown. The management module includes a Switch Fabric switching matrix, a CPU module, and a management channel. Each switching service module includes a Switch switching unit, a CPU module, and a management channel. The business data exchange in the switching business module, and the business data exchange with the SwitchFabric switching matrix, the CPU module is responsible for the management and maintenance of the network protocol, and the management channel interface enables the management module to manage each switching business module. [0003] How modular switches work. When data exchang...
